I'm a teacher, my wife knows not to call during teaching hours. My phone rings during an assembly. I thought, "good timing, but this must be an emergency." I answer and she's subbing loudly. I couldn't understand her. I finally realized she was telling me that one of my daughter's best friends had committed suicide. That was a rough day.
A few months later, my wife called again during the day. This time she was calling to tell me that our oldest daughter was cutting herself. My day was shot.
